To all whom, it ntr/ l concern.-

Be it known that 1, LUTHER O. ORowELL, a citizen of the United States, residing at New York city, county of Kings, and State of New York, have invented certain new and useful Improvements in Sta plingMachines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in stapling mechanism of the kind employed for inserting staples in the folded procluct of high-speed printing-machines.

The mechanism which embodies the invention is more particularly intended for inserting staples in the corners of folded newspapers in order to prevent the fraudulent return of the papers to the publisher after the same have been sold to the customers and read by them, the staple showing whether or not the paper has been opened.

The object of the invention is to provide a stapling mechanism which shall be adapted for use in printing-machines which produce products of varying sizes. As is well known in the art, it is frequently desired to change the form of the output of a printing-machine by varying the number of pages which it contains, and the present invention is directed toward enabling this to be done without extensive changes in the stapling mechanism. To this end the stapling mechanism isconstructed so that it may be quickly adapted to changes in the output of the machine.

Nhile the invention is adapted for the par- I ticular use-above set forth, it is by no means to be restricted thereto, as it is capable of uses in many other relations.

The invention consists in certain constructions and in certain parts, improvements, and combinations, as will be hereinafter described, and fully pointed out in the claims hereunto appended.

In the accompanying drawings, forming a part of this specification, and in which like reference characters indicate the same parts, Figure 1 is a view illustrating diagrammatically the folding mechanism of a printing-machine with the stapling mechanism in place therein in its proper position with relation to the other parts of the machine' Fig. 2 is a plan view of the stapling mechanism, the-view being taken on a plane indicated by-the line2 2 in Fig. 1. Fig. 3 is an end view, on an enlarged scale, of the stapling mechanism, part of one of the stapling-rolls being broken away to more clearly show the interior construction. Fig. 4: is a sectional view taken on the line 4 4: of Fig. 2, the parts being shown in the position they assume when the staple-forming mechanism is about to take the wire length. Fig. 5 is a similar view showing the parts in the position they assume as the staple is being clenched afterinsertion. Fig. 6 is a plan view showing the staple-forming rolls and the wire-feeding devices, a portion of the frame being shown in section and the horn being omitted. Fig. 7 is a sectional view taken on the line 7 7 of Fig. 6 looking in the direction of the arrow. Figs. 8 and 9 are sectional detail views taken on the lines 8 and 9, respectively, of Fig. 4. Fig. 10 is a perspective view of the device for inturning the ends of the staple, Fig. 11 is a side view illustrating the gearing for operating the staple-feeding mechanism. Fig. 12 is a front view showing a modification in which the stapling-rolls also operate as folding-rolls. Fig. 13 is a detail plan View, partly in section, showing the devices for controlling and feeding the wire. Fig. 14: is a perspective view of a folded sheet with a staple inserted in its corner, and Fig. 15 is a sectional detail showing a series of plies of paper with the staple inserted therethrough and clenched.

In the embodiment of the invention which has been selected for illustration in connection with this application A A B B indicate the guiding and fold-laying rollers ordinarily used in connection with a longitudinal folder of common construction. These guiding and fold-laying rollers might, however, equally well receive the product which it is desired to staple from any other source. O is a rotary carrier mounted on a shaft C and provided with the usual folding-blades 0, pins 0, and cutting-blocks 0 and with this carrier cooperates another rotary carrier D, mounted on a shaft D, provided with a knife (Z and pins d. In the form of the invention shown in Fig. 1 a pair of fold-laying rolls E, mounted on suitable shafts, cooperates with the rotating carrier C, the whole forming a rotary folding mechanism of a well known type, which may be used as a collecting mechanism when desired. The folded product passes from the rolls E between a pair of pivoted guides F, which present it to a set of staplingrolls carried on the shafts H I, which rolls after stapling it deliver it to a rotary fly S of well-known construction.

The rotary fi y S is driven by a train of gears Gr (indicated by dotted lines in Fig. 1) from the rotary folding mechanism before described,and the arrangement of gearing is such that the fly-shaft is given one-quarter of a revolution to each half-revolution of the carrier C. The stapling-roll shafts H I are driven from the fly-shaft by a train of gears g, (also indicated in dotted lines in Fig. 1,) the arrangement being such that these shafts are given two revolutions for each quarter-turn of the fly-shaft. Inasmuch as each quarterrevolution of the fly-shaft delivers the folded paper, it will be seen that the stapling-rolls on the shafts H I must make one idle revolutiouthat is, one revolution during which no staple is formed and driven.

The wire W, from which the staples are formed, is taken from any suitable source, as from a spool T, conveniently mounted in the machine. The wire is led through a guide 20, (see Figs. 6 and 13,) which guide is preferably curved and provided with a groove or channel through which the wire passes. This guide preferably delivers the wire to a pair of wire-feeding rolls 21 21, mounted on shafts 22 22. These shafts are preferably intergeared, so that one of them is driven from the other. One of the shafts 22 (herein shown as the lower one) is provided with a beveled gear 23, (see Figs. 2 and 11,) which meshes with a beveled gear 24:. This beveled gear 2% is mounted on a short shaft 25, which shaft is further provided with a gear 26. Beneath the shaft 25 is mounted a shaft 27, carrying gears 28 and 28', and beneath the shaft 27 is mounted a shaft 29, on which is slidingly mounted, by means of a spline and set-screw or in any other convenient way, a pair of gears 30 30 and a gear 30". The gear 30 is one of the gears of the train leading from the fiy-shaft and serves to operate the shaft 29. The gears 26 and 28 have the same number of teeth, and the gears 28 and 30 have the same number of teeth; but the gear 30 has twice as many teeth as the gear 28. When, as shown in Fig. 2, the gear 30 is in mesh With the gear 28, the shaft 27 and the shaft 25, which operates the wire-feeding-roll shaft, have a speed which is twice the speed of the shaft 29. By shifting the gears 30 30 to the right, as shown in Fig. 11, so as to move the gear 30 out of mesh with the gear 28 and bring the gear 30 into mesh with the gear 28, the speed of the shaft 27 and the speed of the shaft 25, with which it is geared, are reduced one-half or to a speed equal to the shaft 29. In other words, when the gear 30 is in mesh with the gear 28 and these gears are operating to drive the wire-feeding-roll shaft and the wire-feeding rolls the wire is fed at twice the speed at which it is fed when the gear 30 is in mesh with the gear 28 and these gears are operating to drive the wire-feeding rolls. Provision is thus made for changing the speed of the wire-feeding devices to correspond with certain other adjustments, which will be hereinafter described.

The feeding-rolls 21 deliver the wire to a wire-presenting mechanism, the oflice of which is at proper times to place a length of wire sufiicient to form a staple in the path of the staple forming devices. This presenting mechanism preferably consists of a block 32, having a forwardly-projecting portion 32, in which is formed a wire-receiving groove 33. This wire-presenting block 32 preferably has secured to it in any convenient way, as by screws, a wire-guiding block 31, having a perforation 31. This wire-guiding block is located between the presenting-block and the wire-feeding rolls and serves to keep the wire under control at all times, and particularly during the movement of the presenting-block, hereinafter described, so that the wire may always be accurately fed to the wire-receiving groove 33. Preferably the mouth of the perforation 31 will be flared so as to allow the block 31 to move without sharply bending the wire.

The block 32 has a movement toward and away from the stapleforming mechanism so that it may at the proper time bring a length of wire into the path of said forming mechanism and at other times hold the wire away from it. While the presenting mechanism may be operated in various ways so as to effect the movement desired this movement is p referably provided for by pivoting the block 32 by means of a stud 3et, which works in a suitable bearing 35, to a bracket K, which is suitably secured to the machine and carries certain parts of the stapling mechanism. The stud 34 has connected to it in any suitable manner an arm 36, which arm is preferably provided with a bowl operating in connection with cam projections 37 on a cam-disk 38, which is carried by the fly-shaft L. The movement of the arm 36 is resisted and its bowl kept in contact with the cam by means of a spring 39, operating against an adjustable collar 40 on a rod 4L1, which rod is pivoted to the arm 36 at one end and at its other end plays through the bent endof a bracket 42', which is suitably secured to the bracket K. The spring 39 has the end opposite to that which bears upon the collar 40 bearing against the bent end of the bracket 42, and thus operates to hold the arm against the cam-disk 38 in an obvious manner. It is apparent that the wire-presenting block 32 by means of the devices just described will normally be held backward away from the stapling-roll and that it will be rocked forward toward the roll whenever one of the cam projections 37 comes in contact with the bowl upon the end of the arm 36. Some of the cam projections 37, or all of them, if it is thought desirable, may be separate from the cam-disk 38 and adjustable thereon, so as to be either in an operative or inoperative position. In the machine shown two of the cam projections 37 are thus made adjustable. This adjustment may be accomplished in various ways. A convenient form. of adjustment, however, is to pivot the cam projections 37 to the cam-disk 38, as shown, the pivot being marked 37. The projections are further provided with threaded pins 37", which engage either one of two sets of holes in the cam-disk 38. \Vhen the pins 37 are caused to engage the outer set of holes in the cam-disk 38, the cam projections are operative and when the said pins engage the inner set of holes the cam projections are rendered inoperative.

The staple forming and inserting mechanism is of the rotary form and is carried ontwo shafts H and I, which are preferably intergeared and one of which carries a gear which forms one of the train leading to the fly-shaft. (See Fig. 2 and dotted lines in Fig. 1.) The staple forming and driving mechanism is mounted on the shaft I and is preferably carried between two rolls 40 41. Each of these rolls serve to support one of the staple-forming blocks 42 43. Each of'these blocks preferably has its outer face located in different planes, the rear portion of the block lying above the front portion. This construction provides each of the blocks with a shoulder, the shoulders being numbered, respectively, 42.. and 43, and these blocks are further provided with grooves 42 43", which grooves extend radially with respect to the axis of the shaft 1, upon which the stapling-rolls are carried. The block 43 is also preferably provided with a cutting edge which cooperates with the edge of the guiding-block 31 to sever the wire.

"hen the wire-presenting block 32 has been rocked into its forward position, its projection 32', which is substantially equal to the space between the staple-forming blocks 42 43, will occupy such a position that the staple'' forming blocks will pass on each side of it. At this time a length of wire which has been fed forward by the wire-feeding rolls will lie in the groove 33 of the block 32. As the staple-forming rolls rotate the cutting edge of the block 43 will act, together with the block 31, to sever the wire, as above described. The shoulders 42 43 will come in contact with the ends of the length of wire just after it is severed and the wire will be carried forward, resting upon the blocks 42 43 and against the shoulders 42 43.

Cooperating with the staple-forming blocks 42 43 is the staple-forming anvil 44, which is secured to the bracketK in any desirable manner. This anvil is curved in form and is located over and lies for a part of its length in the space between the rolls 40, so that the blocks 42 43 will pass on each side of it. As these blocks carrying the length of wire travel onward the wire will be forced by the anvil down into the space between the blocks and into the grooves 42 43". The wire is thus bent up into U shape and the staple is formed. In order that the ends of the staple-legs may be more readily inturned in the clenching operation, which takes place after they have been inserted into the paper, it is desirable to give them a slight inward turn or bend. In order to accomplish this, the anvil 44 is preferably provided upon its sides for a part of its length with grooves 45 and also with plates 46. which are secured to the anvil by screws or in any suitable manner. The plates 46 have in wardlyturned cam projections 47,.the arrangement and contour of these projections being clearly shown in detail view in Fig. 10. As the wire length is carried, forward by the blocks 42 43 and bent up into a staple the ends of its legs pass between the sides of the anvil and the curved cam projections of the plates 46 and are bent by said projections into the grooves 45 in the manner clearly indicated by Fig. 8, the staple thus being given the form shown in the detail view in Fig. 9. The anvil 44 is preferably providedwith a spring 48, which overlies its outer side and projects somewhat beyond its extreme end into the space between its stapling-rolls. The purpose of the spring will be hereinafter stated. I

Mounted between the staple-forming blocks 42 43 is a staple-driver 50. This staple-driver is preferably provided with shoulders 51, which partially embracethe blocks 42 43, and these blocks thus serve to guide the driver in its movement. The driver is also provided with a transverse groove 52, in which the cross-bend of the staple is received. During the wire-receiving and staple-forming operations the staple-driver is retracted into the 61, (see Fig. 6,) which shaft is located in and carried by the roll 41, before described. This I to shaft 61 is a rock-shaft and has projecting from the end opposite to that which carries the arm a crank-arm 62, carrying a bowl 63, which contacts with a stationary cam 64. This stationary cam may be mounted in any suitable or convenient place, but is preferably mounted on the journal in which the shaft I of the roll fl is mounted. The end of the arm 60 opposite to that which engages the staple-driver 5O bears against the spring 65, which is located in a socket 66, carried on a bracket 67, mounted upon the roll 41. It is obvious that as the roll 41 rotates the bowl 63 will follow the contour of the cam 64, being held thereagainst by means of the operation of the spring 65, and the driver will, by the eccentricity of the cam, be caused to reciprocate in and out to drive the staple at the proper time. The shaft H also carries two rolls 7O 71, which lie in the same planes as the rolls 4C0 4:1 of the shaft I. These rolls 7O 71 have secured to them a clenching-plate 79., provided with a groove 73. The office of this clenching-plate and groove is to cleneh the end of the staple and give it the form shown in Fig. 12.

The operation of the machine is as follows: The machine being adjusted, as shown in Fig. 1, the folded web from a longitudinal folder or other suitable source passes between the rolls A and B to and between the carriers (1 D. One set of pins on the carrier (,3 seizes the leading end of the web and carries it forward until the cutter on the carrier D comes into COiiDGIZttiVG relation with one of the cutting-blocks on the carrier C. At this time a sheet length is cut off and tucked down between the rollers E, from which it passes from the guides F to the sta1i ling-rolls 4E0 fl and 71. The wire-feeding rolls 21, which in the machine described are shown as eontimrously-operating rolls, are in the meanwhile acting to feed forward a length of wire sufficient to form a staple, said length passing through the curved guide 20 to these rolls and from them through the guide-block 31 into the groove 33 of the wire-presenting block 32. At the proper time one of the cam projections 37 on the cam 38 strikes the roller on the arm 36 and lifts it, rocking the presenting-block 32 forward so that the length of wire which it carries will be in the path of the staple-forming blocks 4:2 i3, which are carried upon the rolls e0 e1 of the shaft 1 As these rolls rotate the forming-blocks 452 4:3 pass on each side of the projection of the presenting-block and remove the wire there from, the cutting edge of the block 4C3 operating to sever the wire as the length is removed from the presentingblock. The length of wire being new cut oil, it is swept around by the staple-forming blocks, which in connection with the anvil operate to form a staple, the ends of which are iuturned, as before described, by the cam projections 4:7

of the plate 46. As the staple thus formed is swept around to the inserting-point it passes off the end of the anvil 4A, and while still under the control of the stapleforming blocks comes in contact with the spring 48, which acts to steady it and retain it in the forming-blocks in position to be inserted in the traveling folded paper. Just as the staple leaves the anvil ett the arm 60 of the staple driving mechanism is operated through the shaft 61, the arm 62, the roller 63, and the stationary cam 64 to thrust forward the staple and force it through the folded product. After the staple penetrates the folded product it meets the clenching-plate and is clenched in a manner well understood.

The mechanism above described operates to insert a staple through a web which has been twice folded, once longitudinally and once transversely, or it may be a series of superposed webs thus folded. Should it be desired, however, to use the folding mechanism above described as a collecting mechanism also, one set of pins on the carrier C is thrown out and the set of pins on the carrier D is made operative in amanner which is well understood in the art and need not be herein specifically described. \Vhen so adjusted, the folding mechanism will operate to collect two sheets, and it is obvious that the collected sheets will pass between the stapling-rolls only one-half as often as when the folding mechanism is not operated to collect. It is necessary, therefore, to prevent the presenting-block from presenting a staple length of wire to the staple-forming mechanism every second revolution, as here tofore, and arrange it so that it will present a length of wire only once in every fourth revolution. To accomplish this, the pins 37" of the cam projections 37 are taken out, the said projections are turned on their pivots so as to fall inside the circumference of the carrier 38, and the pins are inserted in the inner line of holes so as to secure the projections 37 in place. The Wire-feeding mechanism is also adjusted by throwing the gears 26 and 30 out of mesh and bringing the gears 28 and 30 into mesh. When the machine is thus adjusted, the feeding operation proceeds as before, with the difference that the length of wire is fed only once in every fourth revolution of the stapling-rolls. It is obvious that by providing the carrier 38 with a sufficient number of adjustable cam projections 37 and by further providing a suliicient number of change-gears to control the wire feed, the machine can be arranged to staple a great variety of products.

In some forms of printing-machines now in use the exigencies of space will not permit the insertion of stapling-rolls between the fold-laying rolls of the rotary folder and the rotating fly-delivery. In such cases the foldlaying rolls E and the guides F may be omitted and the stapling-roll shafts H I and the stapling-rolls be located so as to receive the folded product directly from the rotary carrier (J. Such aconstruction is shown in Fig. 12. In this construction the stapling-rolls 40, 4:1, 70, and 71 receive the folded product directly from the tucking-blades c of the rotary carrier C and have the function not only of the stapling-rolls, but also of fold-laying rolls. Additional fold-laying rolls may also be mounted on the shafts H and 1, if desired.

It is obvious that the mechanical details of the machine which has been described as embodying this invention may be varied widely, and many such variations in construction will suggest themselves to skilled mechanics. It is to be understood, therefore, that the invention is not limited to the particular details set forth in this specification, but that it is generic in its nature and includes such variations and changes in mechanical details as fall within its spirit and its scope.
